I want to perform advanced non linear explicit sol 701, I set all the parameter on the basis of research done by me on internet.
well but when I submit my model for analysis it says, processing of nastran failed, does somebody guide me where I am doing mistake and what sort of things I need to keep in mind when perfroming such analysis.
Looking forward to hear from somebody soon.
Thank you in advance for sparing time and consideration.
Solved! Go to Solution.
What is the reason for using SOL701 versus using Advanced Nonlinear Transient (SOL601)? Generally SOL701 is used for for short duration impact type problems with very small time steps.
It would be useful for you to post snapshots of your Advanced Nonlinear Explicit Solver options (settings in the NASTRAN NXSTRAT Solver Parameters dialog box).
Sir, I performed both static and non linear static analysis, from both the test I acheived little deformation.
I want to stiff my model atleast 80 percent, so I switch to advanced non linear explicit 701.
but when I run I got message stating that failed to submit the job
attached please see the snapshots.
What exactly do you mean by stiff the model by 80%?
In any case, unless this is a dynamic loading case, you should use SOL601.
I mean compress the model ateast 80%,
You mean using advanced non linear static analysis. could you please tell me with this analysis is it possible to compress the model.
Yes, you should be able to apply compression loads to the model. Remember to apply the load(s) using a vs Time function. For example, to apply 100 percent of the load over 1 second, you would have a simple vs. Time function with three values:
2, 1 (use to keep the load applied).
Also, set your time step to something like .01 with 100 time steps. If it does not converge, lower the time step.
